NOTES
1. Automatic means that when the controller
stops, the vent valve is opened with a delay
defined by window n. 126; when the controller
starts, the vent valve is immediately closed.
2. On command means that the vent valve is
opened or closed by means of window n. 122.
3. These commands remove the pump motor
supply for a short time. If they are used con-
tinuously, they can cause the pump stopping.

SERVICE OPTIONS
Varian pumping systems will provide many years
of trouble-free operation if the maintenance proce-
dures are observed.
Pumping System cleaning and internal scroll pump
tip seal replacement are recommended when
Pumping System TMP adsorbed current (with
blanked inlet flange) has risen to an unacceptably
high level (>500mA) or when the message “TIP-
SEAL SERV” appears on the TPS-compact front
side display.
The warning message appears after 5000h of op-
eration.
If your TPS-compact exhibits humming or grinding
noises from the scroll pump, a major overhaul
should be done by Varian Vacuum Technologies.
Advance exchange TPS-compact are available to
minimize downtime.
The parts needed for Tip-Seal replacement on the
internal scroll pump are available in the kit de-
scribed in Orderable parts Table. This kit contains
seals and O-rings, and can be obtained from your
Varian dealer.
